Errors When Trying to Delete a Resource
Ok, so in my List view, I added column actions for each row, where one of the actions is to delete that row.
I have my custom dataProvider setup with a deleteOne that takes in the parameters and sends out an API request to delete the request item.
I have also enabled canDelete in my App
For some reason though, when i click the delete action, I get the following errors in my console and deleteOne is never called:

Hi @nick_montoya. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Hmm, I don't know enough to give you a confident answer yet. The error messages you're seeing seem to suggest that there's an issue with the data being passed to the
useDelete
hook or the response from your deleteOne
method in your data provider.
However, without more specific information about your implementation, it's hard to provide a definitive solution. I would recommend checking the following based on the information provided in the extracts:
1. Ensure that your deleteOne
method in your data provider is correctly implemented and returns the expected data structure. According to the documentation (https://refine.dev/docs/tutorial/understanding-dataprovider/create-dataprovider), it should return an object with a data
property.
2. Check the parameters you're passing to the useDelete
hook and the mutate
function it returns. The documentation (https://refine.dev/docs/api-reference/core/hooks/data/useDelete) suggests that you should be passing an object with resource
and id
properties to the mutate
function.
3. Make sure that the canDelete
prop is correctly set in your Edit
component and that the usePermissions
hook is returning the expected data. The documentation (https://refine.dev/docs/api-reference/mui/components/basic-views/edit) provides more information on how to use these.
If you're still having trouble, I would recommend referring to the refine documentation (https://refine.dev/docs) or seeking help from the refine community.

@kapa.ai Okay so this is weird, if I type random gibberish into as the resource name in
mutateDelete
hook that I am using to delete the item, it will invoke my deleteOne and send out an API request fine with that random resource that has never been defined, but if I use my actual reasource name, then it results in those errors mentioned aboveLet me check the knowledge base for you. One moment! :books:
----------------------
This is indeed strange behavior. The
resource
parameter you pass to the mutate
function from useDelete
hook is used as an API endpoint path and is passed to the deleteOne
method in your data provider. If using a random string as the resource
works but using the actual resource name doesn't, it suggests that there might be an issue with how the resource
is being handled in your deleteOne
method or elsewhere in your application.
Here are a few things you could check:
1. Check your deleteOne
method: Ensure that your deleteOne
method in your data provider is correctly handling the resource
parameter. It should be used to construct the API endpoint URL for deleting a record. Here's an example from the documentation (https://refine.dev/docs/tutorial/understanding-dataprovider/create-dataprovider):
2. Check your useDelete
hook: Make sure you're passing the correct resource
and id
to the mutate
function returned by the useDelete
hook. Here's an example from the documentation (https://refine.dev/docs/api-reference/core/hooks/data/useDelete):
3. Check for naming conflicts: Ensure that the resource
name you're using doesn't conflict with any other variables or reserved words in your application.
4. Check your API: If your deleteOne
method and useDelete
hook are correctly implemented, there might be an issue with your API. Ensure that the API endpoint for deleting a record exists and is correctly configured to handle delete requests.
If you're still having trouble, I would recommend referring to the refine documentation (https://refine.dev/docs) or seeking help from the refine community.

@kapa.ai Well the problem is that the deleteOne method never gets invoked when the resource name is set correctly in the
mutateDelete
, so it has nothing to do with the data provider and deleteOne, it has to do with something mutateDelete
is doing before it passes it off to deleteOne, there is some code in between them that is causing this error, what could it be?Let me check the knowledge base for you. One moment! :books:
----------------------
Based on the information provided in the extracts, the
useDelete
hook from Refine uses the deleteOne
method from your data provider as the mutation function. If the deleteOne
method is not being invoked when you pass the correct resource name to the mutate
function, it suggests that there might be an issue with how the useDelete
hook or the mutate
function is being used.
Here are a few things you could check:
1. Check your useDelete
hook: Make sure you're correctly importing and using the useDelete
hook. Here's an example from the documentation (https://refine.dev/docs/api-reference/core/hooks/data/useDelete):
2. Check the parameters you're passing to mutate
: The mutate
function expects an object with resource
and id
properties. Make sure you're passing these correctly. If you're dynamically generating these values, ensure that they're correctly defined at the time you're calling mutate
.
3. Check for naming conflicts: Ensure that the resource
name you're using doesn't conflict with any other variables or reserved words in your application.
4. Check your data provider: Even though you mentioned that the deleteOne
method is not being invoked, it's worth checking that your data provider is correctly set up and passed to the <Refine>
component. The useDelete
hook uses the deleteOne
method from the data provider you pass to <Refine>
.
If you're still having trouble, I would recommend referring to the refine documentation (https://refine.dev/docs) or seeking help from the refine community.

@kapa.ai So my Edit component can delete the resource fine, its just from the List view it's having trouble deleting it, why would it work with the Edit component but not the list?
Let me check the knowledge base for you. One moment! :books:
----------------------
The difference in behavior between the
Edit
and List
views could be due to how the resource
and id
are being passed to the useDelete
hook in each view.
In the Edit
view, the resource
and id
are often obtained from the route parameters, as the Edit
view is typically associated with a specific record. The DeleteButton
component in the Edit
view reads the resource name and id from the route by default, as mentioned in the documentation (https://refine.dev/docs/api-reference/chakra-ui/components/buttons/delete-button).
In the List
view, however, you might be manually passing the resource
and id
to the useDelete
hook or DeleteButton
component. If these values are not correctly defined at the time you're calling the mutate
function, it could lead to the issues you're experiencing.
Here's an example of how you might use the DeleteButton
in a List
view:
In this example, the resource
is "posts" and the recordItemId
is "123". These values should match the resource and id of the record you want to delete.
If you're still having trouble, I would recommend referring to the refine documentation (https://refine.dev/docs) or seeking help from the refine community.

Hey @nick_montoya,
Are you sure that the getList method returns data and total?
https://refine.dev/docs/tutorial/understanding-dataprovider/create-dataprovider/#methods
Probaply you use mutationMode different from pessimistic so when you try a mutation the refine hooks also try to change cache data. If you donβt return a data as not expected, an error occurs.

Thanks for the reply!
Yes this is my getList:
For now, I only have 1 data in my organizations table, so I don't really need the cursor, but its there anyways.
So it looks like it does work on pessimistic mode, but not on optimistic mode or undoable mode
so is it a problem of being able to cache my data locally? how can I solve this? I don't really see where I have control of how
mutateDelete
tries to do this, does it need to match my interface perfectly?subsequent-cyanβ’13mo ago
Just checked out the source code for
useDelete
, it looks like your data
property from the getList
method might not be returning an array all the times (like null
or any non array). Can this be the case?
In your getList
method, it looks like you might benefit from having some type checking from the API response π
Not sure if this is the real case but it looks like response.body.data
is not always an array.
BTW, about the error you've mentioned in the first message Cannot read properties of undefined (reading 'status')
looks like its realted with the onError
method of your authProvider
π€
Let me know when you can validate the getList
method always returning an array πforeign-sapphireβ’13mo ago
oh ok interesting, ill try to fix that one
yea that's definitely possible, although my API should always be sending back an array even if its empty, but ill take a look
What is
status
supposed to represent for the onError
hook? Is that just the status code? Is it supposed to be placed in the error
or error.response
or somewhere else in the error when I return it? Is there a detailed API doc on all of these functions so I know excatly what my functions are supposed to return?
just added a type check to my getList so it should be returning an array when I try to delete the resource in the list view because it doesn't throw an error on the console/app UI:
The thing is though, getList
doesn't run when i hit the delete action, as the console log inside of it never gets ran
